+# UserNovelDataService Backfill Scripts
+
+SQL scripts for backfilling data from UserService and NovelService into UserNovelDataService.
+
+## Prerequisites
+
+1. **Run EF migrations** on the UserNovelDataService database to ensure all tables exist:
+   ```bash
+   dotnet ef database update --project FictionArchive.Service.UserNovelDataService
+   ```
+
+   This will apply the `AddNovelVolumeChapter` migration which creates:
+   - `Novels` table (Id, CreatedTime, LastUpdatedTime)
+   - `Volumes` table (Id, NovelId FK, CreatedTime, LastUpdatedTime)
+   - `Chapters` table (Id, VolumeId FK, CreatedTime, LastUpdatedTime)
+
+## Execution Order
+
+Run scripts in numeric order:
+
+### Extraction (run against source databases)
+1. `01_extract_users_from_userservice.sql` - Run against **UserService** DB
+2. `02_extract_novels_from_novelservice.sql` - Run against **NovelService** DB
+3. `03_extract_volumes_from_novelservice.sql` - Run against **NovelService** DB
+4. `04_extract_chapters_from_novelservice.sql` - Run against **NovelService** DB
+
+### Insertion (run against UserNovelDataService database)
+5. `05_insert_users_to_usernoveldataservice.sql`
+6. `06_insert_novels_to_usernoveldataservice.sql`
+7. `07_insert_volumes_to_usernoveldataservice.sql`
+8. `08_insert_chapters_to_usernoveldataservice.sql`
+
+## Methods
+
+Each script provides three options:
+
+1. **SELECT for review** - Review data before export
+2. **Generate INSERT statements** - Creates individual INSERT statements (good for small datasets)
+3. **CSV export/import** - Use PostgreSQL `\copy` for bulk operations (recommended for large datasets)
+
+## Example Workflow
+
+### Using CSV Export/Import (Recommended)
+
+```bash
+# 1. Export from source databases
+psql -h localhost -U postgres -d userservice -c "\copy (SELECT \"Id\", \"OAuthProviderId\", \"CreatedTime\", \"LastUpdatedTime\" FROM \"Users\" WHERE \"Disabled\" = false) TO '/tmp/users_export.csv' WITH CSV HEADER"
+
+psql -h localhost -U postgres -d novelservice -c "\copy (SELECT \"Id\", \"CreatedTime\", \"LastUpdatedTime\" FROM \"Novels\") TO '/tmp/novels_export.csv' WITH CSV HEADER"
+
+psql -h localhost -U postgres -d novelservice -c "\copy (SELECT \"Id\", \"NovelId\", \"CreatedTime\", \"LastUpdatedTime\" FROM \"Volume\" ORDER BY \"NovelId\", \"Id\") TO '/tmp/volumes_export.csv' WITH CSV HEADER"
+
+psql -h localhost -U postgres -d novelservice -c "\copy (SELECT \"Id\", \"VolumeId\", \"CreatedTime\", \"LastUpdatedTime\" FROM \"Chapter\" ORDER BY \"VolumeId\", \"Id\") TO '/tmp/chapters_export.csv' WITH CSV HEADER"
+
+# 2. Import into UserNovelDataService (order matters due to FK constraints!)
+psql -h localhost -U postgres -d usernoveldataservice -c "\copy \"Users\" (\"Id\", \"OAuthProviderId\", \"CreatedTime\", \"LastUpdatedTime\") FROM '/tmp/users_export.csv' WITH CSV HEADER"
+
+psql -h localhost -U postgres -d usernoveldataservice -c "\copy \"Novels\" (\"Id\", \"CreatedTime\", \"LastUpdatedTime\") FROM '/tmp/novels_export.csv' WITH CSV HEADER"
+
+psql -h localhost -U postgres -d usernoveldataservice -c "\copy \"Volumes\" (\"Id\", \"NovelId\", \"CreatedTime\", \"LastUpdatedTime\") FROM '/tmp/volumes_export.csv' WITH CSV HEADER"
+
+psql -h localhost -U postgres -d usernoveldataservice -c "\copy \"Chapters\" (\"Id\", \"VolumeId\", \"CreatedTime\", \"LastUpdatedTime\") FROM '/tmp/chapters_export.csv' WITH CSV HEADER"
+```
+
+**Important**: Insert order matters due to foreign key constraints:
+1. Users (no dependencies)
+2. Novels (no dependencies)
+3. Volumes (depends on Novels)
+4. Chapters (depends on Volumes)
+
+### Using dblink (Cross-database queries)
+
+If both databases are on the same PostgreSQL server, you can use `dblink` extension for direct cross-database inserts. See the commented examples in each insert script.
+
+## Verification
+
+After running the backfill, verify counts match:
+
+```sql
+-- Run on UserService DB
+SELECT COUNT(*) as user_count FROM "Users" WHERE "Disabled" = false;
+
+-- Run on NovelService DB
+SELECT COUNT(*) as novel_count FROM "Novels";
+SELECT COUNT(*) as volume_count FROM "Volume";
+SELECT COUNT(*) as chapter_count FROM "Chapter";
+
+-- Run on UserNovelDataService DB
+SELECT COUNT(*) as user_count FROM "Users";
+SELECT COUNT(*) as novel_count FROM "Novels";
+SELECT COUNT(*) as volume_count FROM "Volumes";
+SELECT COUNT(*) as chapter_count FROM "Chapters";
+```
